really isn’t rocket science...















Stops limescale...dead in the water


Just drop into the cup section of your dishwasher...





And your loft water tank...






From just 2p a day...



We pledge that if it doesn’t work - we’ll give you your money back*



What is CalcStop?

It’s a time-proven and extremely effective way of stopping limescale...dead - uses a food-grade material.


How long does it last?

A whole year, so it costs just 2p a day! We recommend that you monitor its use if your water use is high. Once it has broken down to a small pile, replace it.


Is polyphosphate in water ok?

Yes. Polyphosphates are legally permitted additives that are widely used to aid processing, or to improve eating quality of many foods, particularly meat and fish products.


It’s cheap, effective, and really easy to use. Simply drop the bag into your water tank, loo cistern, or your dishwasher. For washing machines email us.
